Verdict
The clearest difference is in-app purchases: Chess Music at none against DEEMO's 10. Chess Music also leads on update cadence (every 4 days vs every 2 months) and review sentiment (100% vs 91%). DEEMO's advantage is ratings volume (5.1K vs 3) and chart position (#14 vs #138). On price, rating, ads and device support there is nothing between them.
